Actually, the response he's received has been quite rational, explicable, and warranted.
It's a direct result of the way he chose to promote (and discuss) his book—by self-aggrandizing, calling others "weak", mocking titled players and world champions (both past and present), and insulting any who dare to question his credibility (or his chess notions).
Had he simply came on and left his ego at the door, I'm sure the reaction would've been quite different.
Granted, it's inevitable that one will encounter backlash when promoting a book—but such is the life of any author. Picking fights with the detractors and critics isn't the right way to win them over. All that's done is drag things down a muddy path, full of insults, hostility, and outlandish claims.
On the contrary, I am posting good games all the time. Here one more of Carlsen. It is not my fault people don't spot the good chess content.

Only one more?
At first, they accused GWTR so.
Ask him if he is one more sock puppet.
